ATIS and the SIP Forum have announced the formation of a Joint Task Force to fully specify an IP communications network-to-network interface (NNI) between North American service providers. The Joint Task Force will ensure all service interconnection between providers occurs at the Internet Protocol (IP) level.

By enabling ubiquitous IP-based interconnection, the new Task Force will support wide-scale availability of IP-based voice services, and lay the groundwork for ubiquitous advanced real-time communications such as high-definition voice, point-to-point video calling, and multimedia text across wireless, wireline and cable providers.
